Equilibrium constants aren't changed if you change the concentrations of things present in the equilibrium. The only thing that changes an equilibrium constant is a change of temperature.
The position of equilibrium is changed if you change the concentration of something present in the mixture. According to Le Chatelier's Principle, the position of equilibrium moves in such a way as to tend to undo the change that you have made.

ViviThe dissociation constant describes the extent to which a compound breaks apart into its ions in a solution, specifically for weak acids or bases. The equilibrium constant, on the other hand, describes the ratio of product concentrations to reactant concentrations at equilibrium for a chemical reaction.

What is the relationship between the equilibrium constant (Keq) and the acid dissociation constant (Ka)?
The equilibrium constant (Keq) is the ratio of products to reactants at equilibrium in a chemical reaction, while the acid dissociation constant (Ka) specifically refers to the dissociation of an acid in water. The relationship between Keq and Ka is that Ka is a specific type of equilibrium constant for acid dissociation reactions. In other words, Ka is a special case of Keq for acid-base reactions.
What is the relationship between the equilibrium constants Kb and Ka in a chemical reaction?
The equilibrium constants Kb and Ka in a chemical reaction are related by the equation Ka Kb Kw, where Kw is the equilibrium constant for water. This relationship shows that the product of the acid dissociation constant (Ka) and the base dissociation constant (Kb) is equal to the equilibrium constant for water.
What is the difference between the equilibrium constant Kf and the solubility product constant Ksp in a chemical reaction?
The equilibrium constant Kf measures the extent of a reaction at equilibrium, while the solubility product constant Ksp measures the extent of a substance dissolving in a solution.
How can one determine the equilibrium constant Kp from the equilibrium constant Kc?
To determine the equilibrium constant Kp from the equilibrium constant Kc, you can use the ideal gas law equation. The relationship between Kp and Kc is given by the equation Kp Kc(RT)(n), where R is the gas constant, T is the temperature in Kelvin, and n is the difference in the number of moles of gaseous products and reactants. By using this equation, you can calculate the equilibrium constant Kp from the given equilibrium constant Kc.
What are the key principles of chemistry that are essential for understanding the concept of ka2?
The key principles of chemistry essential for understanding the concept of Ka2 include understanding acids and bases, equilibrium reactions, and the concept of dissociation. Acids and bases are substances that can donate or accept protons, while equilibrium reactions involve the balance between reactants and products. Dissociation refers to the breaking apart of a compound into its ions in a solution. These principles are crucial for comprehending the concept of Ka2, which is the equilibrium constant for the dissociation of a weak acid.

What is the Difference between static equilibrium's and dynamic equilibrium?
Static equilibrium refers to a system at rest where all forces are balanced, while dynamic equilibrium refers to a system in motion where the rate of change is constant. In static equilibrium, objects are stationary, while in dynamic equilibrium, objects are moving at a constant speed and direction.

Why can the concentration of water be ignored in the equilibrium expression for water?
The concentration of water remains relatively constant compared to other reactants/products in solution, so it does not significantly affect the equilibrium constant. Additionally, water is a solvent that is usually present in large excess, so changes in its concentration have minimal impact on the equilibrium position.
What is the relationship between the rate constant (ka) and the equilibrium constant (kb) in a chemical reaction?
The rate constant (ka) and the equilibrium constant (kb) in a chemical reaction are related by the equation: ka kb / (1 - kb). This equation shows that the rate constant is inversely proportional to the equilibrium constant.
How was the equilibrium constant of a reaction determined?
The equilibrium constant of a reaction is typically determined experimentally by measuring the concentrations of reactants and products at equilibrium, and then applying the law of mass action to calculate the constant. Alternatively, the equilibrium constant can also be calculated from thermodynamic data using the relationship between free energy change and equilibrium constant.
What is the relationship between the equilibrium constant and the rate constant in a chemical reaction?
The equilibrium constant (K) and the rate constant (k) in a chemical reaction are related but represent different aspects of the reaction. The equilibrium constant describes the ratio of products to reactants at equilibrium, while the rate constant determines the speed at which the reaction occurs. The two constants are not directly proportional to each other, as they represent different properties of the reaction.
What is the relationship between the Delta G equation and the equilibrium constant (Keq)?
The relationship between the Delta G equation and the equilibrium constant (Keq) is that they are related through the equation: G -RT ln(Keq). This equation shows how the change in Gibbs free energy (G) is related to the equilibrium constant (Keq) at a given temperature (T) and the gas constant (R).
